  • WEAR INDICATOR SYSTEM FOR OFFSHORE CORROSION PROTECTION COVERING SYSTEMS
    Publication number: 20130284296
    Abstract: A corrosion protected metal pipe for installation in an offshore structure or for producing a pipeline laid in water is provided. The metal pipe has an at least two-layer covering on the pipe with a lower layer facing the pipe and an upper layer on a side of the lower layer not facing the pipe is provided. The layers are formed such that the lower layer is electrically conductive and the upper layer is electrically insulating, the lower layer is optically contrasting to the upper layer, or the lower layer is electrically conducting and optically contrasting to the upper layer and the upper layer is electrically insulating. Thus, in the event of damage to the layer or layers lying above, a visual or electrical signal can be detected. Damage to the corrosion protection covering can therefore be detected easily and, if appropriate, reported by remote monitoring.

  • COATED METALLIC ARTICLE
    Publication number: 20130287981
    Abstract: A method for coating of a metallic article is provided. According to the method, the metal surface is coated with a composition which comprises a polymer or comprises a two-component system that reacts to form a polymer following application to the metal surface. The composition comprises 70-2700 meq/kg olefinic double bonds which leads to stronger adhesion and to increased corrosion resistance.

  • HAND-HELD MACHINE TOOL AND CONTROL METHOD
    Publication number: 20130284473
    Abstract: A hand-held machine tool includes a tool accept for mounting a chiseling tool on an operating axis. A pneumatic hammer mechanism includes an exciter, driven back and forth by a motor about a stroke between a dead point distant from the tool and a dead point near the tool, a hammer moved back and forth on the operating axis between a reversal point distant from the tool and a point of impact, and a pneumatic chamber sealed by the exciter and the hammer, which couples the movement of the hammer to the movement of the exciter. A damping device increases the pressure in the pneumatic chamber when the exciter during its motion in the direction to the dead point distant from the tool has approached to less than half the stroke to the dead point distant from the tool.

  • MACHINE TOOL
    Publication number: 20130277077
    Abstract: A hand-held machine tool includes a tool accept for mounting a chiseling tool on an operating axis. A pneumatic hammer mechanism includes a hammer mobile on an operating axis, an exciter, and a pneumatic chamber sealed by an exciter and the hammer, which couples the movement of the exciter to the hammer. The exciter is driven by a motor and moves back and forth between a frontal dead point distant from the tool and a dead point near the tool. A damper device includes a supercharger and a controlled outlet valve. The controlled outlet valve allows air to flow from the supercharger into the pneumatic chamber when the exciter is in the proximity of the dead point distant from the tool.

  • TOOL RECEPTACLE
    Publication number: 20120313333
    Abstract: A tool receptacle is disclosed. The tool receptacle has a spindle which has a receiving area for receiving a tool and an elongated hole which is open into the receiving area in a radial direction. A barrier element disposed in the elongated hole projects into the receiving area and is movable in the elongated hole. A slider is used for sliding the barrier element to an output-side end of the elongated hole, where the slider is subject to the application of force by a first spring against an insertion direction. A radial limit stop forces the barrier element in the radial direction to engage in the receiving area. The radial limit stop is displaceable to enable a radial movement of the barrier element out of engagement with the receiving area. A second spring applies a spring force to the radial limit stop against the insertion direction.

  • In-Memory Database For Multi-Tenancy
    Publication number: 20120173589
    Abstract: An in-memory database server hosting a tenant of a multi-tenant software architecture can receive a definition of a custom data field that is unique to an organization having isolated access to the tenant. The custom data field can extend a standard table defined by central metadata stored at a system tenant of the multi-tenant software architecture. Tenant private metadata that includes the definition can be stored in memory accessible only to the tenant. A tenant-dependent table that includes the custom data field can be formed, for example by retrieving central metadata defining the standard table from the system tenant and adding the custom data field using the definition. The tenant-dependent table can be presented for access via a database client at the organization. Related systems, articles of manufacture, and computer-implemented methods are disclosed.

  • POWER TOOL AND CONTROL METHOD
    Publication number: 20110303429
    Abstract: A power tool and control method is disclosed. The power tool has a striker, which is guided along an axis parallel to an impact direction. A pneumatic chamber has a volume which varies with a movement of the striker along the axis. A valve device that is actuatable depending upon the movement direction of the striker connects the pneumatic chamber with an air reservoir. The valve device is actuated to open in the case of a movement of the striker in the impact direction and in the case of a movement of the striker against the impact direction is actuated to throttle or close. The throttled or closed valve device restricts an air flow flowing through it to a maximum of one tenth of the value as compared to the air flow in an opened position.
